Bought a style bar and am very frustrated with it, how do you install one of these? cause when its all bolted in how is the plastic interior peice fit around it with two individual holes from the factory boilts that went through it, one for the seat belt and one for the original brace. No directions were sent with the bar so I'm shootin the dark with this and bout to send it back as I look at it and say to myself there is no way this can work, unless I'm missing somthin that I just don't see.
